2 Claims. (Cl. 21815) This invention relates to eyeleting machines andmore particularly to raceways as used in such machines to supply eyeletshaving oblong barrels to a spindle of corresponding shape carried by oneof the eyelet-setting tools. The eyelets illustrated herein have barrelsof oval cross-section and the invention is intended to provide forhandling not only eyelets of that type but also eyelets having barrelsof rectangular oblong shape.

In providing shoe uppers with oblong eyelets for the lacings, it hasheretofore been the practice to arrange such eyelets in the relationillustrated, for example, in United States Letters Patent 1,722,286,granted July 30, 1929, on my application. According to the disclosure inthat patent, the major diameters of the eyelet barrels lie in a lineparallel with the adjacent edge of the upper over which the lacing isintended to extend, but a demand has now arisen for an eyeleting machinethat will place the eyelets so that their major diameters will lie atright angles to the lacing edge of the upper.

In all former raceways for handling oblong eyelets the eyelet-guidingchannels have open de-' livery ends through which the. eyelets may beConsequently, an object of the present invention is to provide a racewayof the type that may be operated with sidewisereciprocation to supplyoblong eyelets to an oblong spindle of which the major diameter lies atright-angles to the lines of reciprocation of the raceway. Theexpression oblong eyelets is intended to characterize thecross-sectional shape of the barrels of the eyelets without regard tothe shapes of the eyelet flanges and is intended to include both ovaland rectangular oblong shapes.

The raceway illustrated herein is like former raceways in that itseyelet-guiding strips are spaced according to the minor diameterofoblong barrels, wherefore the major diameters of the barrels aremaintained approximately parallel with their path of travel therein, butthe raceway differs from prior raceways in that its.

delivery end is closed but has provisions for re moval of oblong eyeletsfrom one side thereof while the major diameters of the eyelets lie atright-angles to the lines of reciprocation of the delivery end. For thispurpose a wide notch is 5 formed in one side of the raceway to clear thespindle, and herein lies the problem of maintaining control or theeyelet at the delivery end.

' The width of the notch must exceed the major diameter of the spindle,and the flange of the eyelet must bridge the notch. The provision ofnotch of large enough dimensions leaves so little supporting surface forthe flange. of the eyelet that other means are required to prevent theeyelet from tipping and falling through the notch.

To satisfy this requirement the invention provides a spring-biasedmember arranged to guide the leading eyelet in the raceway across thenotch by engagement with a major side of the barrcl. This guiding memberis, in effect, an extension of the guiding strip that terminates at thenotch to clear the spindle, and although it projects only part wayacross the notch, its extent of projection is enough to maintain thebarrel upright until the flange of the eyelet bridges the notch andfinds support at the opposite side thereof. The eyelet is thus preventedfrom tipping as it slides across the not i. Another spring-biased memberlocated at the opposite side of the notch projects toward the onefirstmentioned, each of them partially closing the gap through which theeyelet barrel is finally removed, and both of them being effective tomaintain the eyelet in spindle-receiving position.

Referring to the drawings,

The raceway is designed to be mounted and operated according to Fig. lin the patent abovementicned, which figure is reproduced in the presentdrawings as Fig. 4 with appropriate changes such the substitution of thenew type of raceway, a corresponding arrangement of the setting tools,and omission of certain parts not necessary for we purposes of thepresent disclosure. The raceway assemblage has provisions for mountingit on the left-hand side of the frame $3 to which it is connected by avertical fulcrum pin ii. This mounting enables the delivery end of theraceway to be reciprocated sidewise in lines indicated by arrow A inFig. 1, its movement to the left serving to carry an eyelet intoregister with the spindle l2 of an eyeletinserting tool i3, and itsmovement in the opposite direction serving to remove the eyelet from theraceway and to clear the path of the tool I3. As shown in 1, the spindlel2 and the barrels id of the two eyelets are of oval cross-section.

The raceway comprises a base plate l5 and two cooperative eyelet-guidingstrips l6 and I! mounted thereon but spaced therefrom as usual in suchconstructions. The guiding edges of the strips are spaced one from theother in accordance with the minor diameter of the oblong barrels M. Thearrow B represents the direction in which the eyelets travel in theraceway. A notch 28 is formed in the base plate E5 to receive thespindle i2 and its open end is at the left to permit the raceway to moveto the right after delivering an eyelet to the spindle. Considering theside 2! of the notch as the nigh side because the eyelets approach thenotch from that side, the guiding strip I6 is terminated at the nighside but the strip i? is longer to guide the eyelets across the notch.The flanges of the eyelets are seated on the base plate i5 and thebarrels extend upwardly therefrom. The eyelets are adequately controlledby the strips (6 and i1 until they reach the nigh side 25 of the notch,but since the eyelets must slide a considerable distance beyond the endof the strip IS, the latter is not effective to keep the flanges of theeyelets on the ledge 21 of the base plate as shown in Fig. 2 or tomaintain the barrels M upright. It is therefore necessary to provideother means to maintain these conditions as the eyelets slide across thenotch, for if they are permitted to tip or slide to the left, they willfall through the notch.

Consequently, to insure adequate support and control of the eyelets atthis point, the raceway is provided with a spring-biased member 22, theeyeletengaging portion 23 of which is more clearly shown in Fig. 2. Thisportion 23 lies on the upper surface of the shorter strip l6 and serves.in effect, as an extension thereof, although it projects only part wayacross the notch 20. Its extent of projection is suflicient, however, tomaintain the flanges of the eyelets on the ledge 2? and to maintain thebarrels i4- upright until the leading edges of the eyelets have crossedthe notch and become lodged on the base plate at the far side of thenotch, as illustrated in Fig. 3.

The spring-biased member 22 spans the strip i7 and is seated upon thebase pate !5 to which it is connected by a pivot stud 2d. The springbias is provided by a light tension spring 25 one end of which isengaged with a hole in the member 22 and the other end of which isengaged in a hole in an ear 25 formed on or affixed to the base plate.As represented in Fig. l, the eyelet-engaging extremity of the member 22is broken away to avoid obscuring the nigh side 2| of the notch; but thenormal position of the portion broken away is represented by dottedlines. A stop 24 is provided to prevent the eyelet-engaging portion 23from being projected too far across the notch 20.

When an eyelet has advanced to a position in register with the notch 28,its barrel is arrested by a stop 30 which, as shown in Fig. l, isprovided by a shoulder formed at the delivery end of the guiding strip17. Turning movement and escape of the eyelet at this point areprevented by the tip of a spring-biased member 38 that projects part wayacross the notch 20 toward the portion 23 of the member 22. The gapbetween the tips of the members 22 and 3| is slightly less than themajor diameter of an oblong barrel I 4 (see Fig. 3) but an eyelet oncelodged as last described can be removed from the raceway by the spindleI 2 when the raceway is moved to the right. The barrel I4 then forcesthe members 22 and 3| away from each other, but they close the gapbefore the next eyelet in the raceway requires their control. The member3| is seated on the base plate l5 and connected thereto by a pivot stud32. A compression spring 33 maintains it normally in the position shownin Figs. 1 and 3.

When an eyeleting machine of the type illustrated in the patentabove-mentioned is equipped with a raceway constructed in accordancewith this invention and with oblong eyelet-setting tools correspondinglyarranged, it wi l insert the eyelets in the relation pictured in Fig. 5.In this figure 34 represents a portion of a shoe quarter and 35 is thelacing edge thereof. The major diameters of the eyelets lie at rightangles to the edge 35. This edge is the one by which the work is guidedwhile the machine is in operation.

Referring to Fig. 4, the eyelet-inserting tool 13 is afiixed to theupper end of a vertical bar 38 that inserts the eyelets with upwardmovement, the operation of the bar being derived from a power-drivencamshaft 38 through the medium of a lever 39.

A horizontal work-supporting table indicated at 3B is provided with anedge-gage M and with a hardened steel punch-block 42. A combined punchand setting tool 43, of oval shape corresponding to that of the tool I3,is carried by an upper bar 44 to which vertical reciprocation andsidewise reciprocation are imparted by coordinated mechanisms not shownherein but which produce a four-way motion of the tool 45%; viz., first,a downward motion against the punch-block; sec- 0nd, at sidewisework-feeding motion to the left which places the tool 43 in alignmentwith the tool I3; third, upward movement to retract the tool 43 from aclenched eyelet; and fourth, a sidewise movement to the right tocomplete the cycle. The tool 43 dwells at the completion of itsworkfeeding stroke while the lower tool i3 inserts an eyelet andclenches it.

The raceway is affixed to a carrier and this carrier is the elementconnected to the frame ID by the vertical fulcrum pin H. The motion forreciprocating the delivery end of the raceway sidewise is derived from acam 46 carried by the shaft 38 and is communicated to the forward end ofthe carrier 45 by a. train of connections compris-- ing a lever 48, a,link 49, a bell-crank lever 50, and a link 51. The lever 53 is suspendedfrom a horizontal fulcrum H but the bell-crank lever 50 is mounted on avertical fulcrum.

Since oblong eyelets are used only for visible eyeleting and sincemachines of the type herein disclosed are organized to insert theeyelets below rather than above the work, the operator places the liningof a shoe quarter uppermost for this kind of work.

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is:
